WebThis 0.1% aqueous bromothymol blue solution (also known as Bromthymol Blue) is a commonly used pH indicator. Bromothymol blue changes color over a pH range from 6.0 (yellow) to 7.6 (blue). It is a good indicator of dissolved carbon dioxide (CO 2) and other weakly acidic solutions. WebThus, after a short time, the surface of the indicator solution changes color: from blue to yellow if you’re using bromothymol blue or from purple to pale pink if you’re using cabbage-juice indicator. This color change indicates …

WebJul 20, 2024 · Since bromothymol blue is green at a pH of 6 and blue at a pH of 8, we conclude that the pH is between these two limits. A more precise result could be obtained by comparing the color in the tap water with that obtained when two drops of indicator solution are added to buffer solutions of pH 6.5 and 7.5. WebBromothymol blue is an indicator that is effective at a pH range of 6.0-7.6, with the indicator appearing yellow below this range and blue above this range. Bromothymol blue Choose...is notis a good indicator when testing the buffer capacity of a pH=5 buffer with the addition of base. WebBromothymol blue changes color depending on the acidity of the solution. It is yellow at pH values below 6, blue at pH values above 7, and green at pH values between 6 and 7.6. … hour sign template free
